Journeyman III

regular FPS drop/lag every ~half second after update to 18.5.1


I have RX480 and i updated my drivers today to version 18.5.1 (clean install option) and something is wrong -  i get fps drop with screen lag every ~1 second. Before driver update everything was fine, game ran smoothly on 120fps (cap). Switching to vsync "on" helps a little but not resolves problem. I dont know driver version prior to update but it was from something dated ~06/2017 and it worked well, now it is bad.

Game is Wolfenstein 2, here is video with statistics, look closely to lags as i move my screen around, also have a look on red spikes and fps drops on statistics in upper right corner.

I tried changing various game settings, i even went to "LOW" settings but it the same problem on low or high settings.

I also tried PUBG and Mass Effect 3, same thing happens so it is not game dependant.

GPU is not throttling, temperatures are fine, nothing beside driver update changed.

DDU in safe mode -> 18.6.1 clean install.

Hello, unfortunately this didn't help. It was good at the beginning and i was already thinking it worked  but after 10 seconds from loading game it started again.

I also tried to turn off amd-freesync (i have screen supporting it) but this was also not the case. Now i am changing various graphical options in game but at the moment nothing seems to work.


Do you have 2 monitors connected?


Only 1 monitor, also i made sure integrated cpu graphic card is disabled in bios.


Please try updating to 18.6.1 and let me know if you experience the same issue.
